A little more expensive but better description.

I have glow in the dark sights for my P290, but they actually came with it and I dont know what the add-on part is called for a P238.

Yep, they glow. I have the Meprolight sights on a Kimber 1911.

I don't have a set, so someone back me up here, but they are Tritium. it's a mildly radioactive isotope that has a half life around 10-12 years. meaning that it doesn't need exposure to light or anything to make it glow, it's self-sustaining just grows slowly dimmer over time.

as opposed to glow in the dark paint or coloring that needs to be recharged with light often.

[OakRidgeStars]

You are correct. They are Tritium sights.

So apparently they use about 1 milligram?

Less radioactive than the average smoke detector.
